Abstract
A reserved pipeline system for cooling water comprises a main pipeline of domestic water and a main water supply pipeline of production circulation water, wherein the main pipeline of the domestic water is communicated with the main water supply pipeline of production circulation water through a connecting pipeline, a valve and a one-way valve are arranged on the connecting pipeline, and the water of the main pipeline of the domestic water controlled by the one-way valve flows to the main water supply pipeline of the production circulation water through the connecting pipeline. The reserved pipeline system for the cooling water has the advantages of being simple in structure, small in occupied area, space-saving, small in investment, free of operation at ordinary times, small in maintenance capacity and operation cost, capable of being used as a reserved supplementary water system, completely independent of the original cooling water system, and free of the influence of the original cooling water system, and being provided with high safety factor. People can complete the operation just by opening the valve under emergency circumstances, Moreover, due to the installation of the one-way valve on the pipeline, the production circulation water can not flow to the domestic water so that no pollution to the domestic water can be caused.
Description
Technical field
The utility model relates to a kind of cooling water spare duct system.
Background technique
In the copper plate/strip production process, can produce a large amount of heat, especially oven and annealing furnace from ingot casting heating, hot rolling to milling the production processes such as face, roughing, annealing, finish rolling, cleaning, must there be continual cooling circulating water to guarantee Operation safety.The reasons such as cooling water system for subsequent use is large owing to floor space, the operation construction is inconvenient, investment is large, when design or Specific construction, do not consider independently cooling water system for subsequent use, or just increase reserve pump at circulating pump room, with ditch the using and the reserved pipe-line system is installed between circulating pump room and cooling equipment, there is potential safety hazard in above-mentioned recirculating cooling water system for subsequent use commonly used in normal productive process.Mainly be with the corruption of ditch pipeline rust leak, the cooling pond cleaning, pump house has a power failure and when other fortuitous events occurring, intrinsic cooling water system for subsequent use often can not really play effect for subsequent use, causes cooling water to stop transport, produce and stop production.Therefore, when above-mentioned situation occurring, need one to overlap really reliably spare duct system, to guarantee to produce normal operation.
Summary of the invention
The problem that the utility model is large for present special cooling water system floor space for subsequent use, the operation construction is inconvenient, investment is large has proposed the cooling water spare duct system that a kind of floor space is little, simple to operate, cost is low.
Cooling water spare duct described in the utility model system, comprise domestic water total pipeline and the total feedwater piping of production cycle water, it is characterized in that: be communicated with by connecting tube between described domestic water total pipeline and the total feedwater piping of described production cycle water, valve and one-way valve are set on the described connecting tube, and the water that described one-way valve is controlled in the described domestic water total pipeline flows to the total feedwater piping of described production cycle water by connecting tube.
Described domestic water total pipeline, the total feedwater piping of described production cycle water and described connecting tube all adopt seamless Coating Steel Pipe.
During normal operation, valve closing in the cooling water spare duct system, cooling water from pump house through the total feedwater piping of production cycle water to each cooling unit, under the case of emergency, close all inlet valves of original cooling water system, open valve on the connecting tube of cooling water spare duct system, just can realize so in a short period of time the handoff-security of cooling water, guarantee is to apparatus cools, finally still get back to hot-tub according to former circulating backwater pipeline after the cooling water work, recycle, guarantee the normal operation of equipment; In addition, when production cycle water needs supplementing water, also can be by opening valve to the moisturizing of production cycle water system.
The beneficial effects of the utility model are: simple in structure, floor space is few, saves the space, utilize original each recirculated cooling water pipeline system of branch, compare with a cover standby system independently, saved cover pump house and a pond, simple to operate, easy to maintenance, operating cost is low; Little investment is in an emergency and only need opens just energy complete operation of valve, owing to not moving, so maintenance is few, operating cost does not almost have at ordinary times, and meet national energy-saving and reduce discharging policy, applied range, safety coefficient is high; Can be used as make-up system for subsequent use, because this system is connected with plant area domestic water pipeline, the satisfied condition that puts into operation the most important thing is to be totally independent of former cooling water system at any time, is not subjected to the impact of former cooling water system, has very high safety coefficient; Because on the pipeline one-way valve is housed, production cycle water can not enter domestic water, can not pollute to domestic water.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Cooling water spare duct described in the utility model system, comprise the total feedwater piping 2 of domestic water total pipeline 1 and production cycle water, be communicated with by connecting tube 3 between described domestic water total pipeline 1 and the total feedwater piping 2 of described production cycle water, valve 31 and one-way valve 32 are set on the described connecting tube 3, and the water in the described domestic water total pipeline 1 of described one-way valve 32 controls flows to the total feedwater piping 2 of described production cycle water by connecting tube 3.
Described domestic water total pipeline 1, the total feedwater piping 2 of described production cycle water and described connecting tube 3 all adopt seamless Coating Steel Pipe.
During normal operation, valve 31 in the cooling water spare duct system is closed, cooling water from pump house through the total feedwater piping 2 of production cycle water to each cooling unit, under the case of emergency, close all inlet valves of original cooling water system, open valve 31 on the connecting tube 3 of cooling water spare duct system, just can realize so in a short period of time the handoff-security of cooling water, guarantee is to apparatus cools, finally still get back to hot-tub according to former circulating backwater pipeline after the cooling water work, recycle, guarantee the normal operation of equipment; In addition, when production cycle water needs supplementing water, also can be by opening valve 31 to the moisturizing of production cycle water system.
The described content of this specification embodiment only is enumerating the way of realization of model utility design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
